dealers. This manual is addressed to Piaggio service mechanics who are supposed to have a basic
knowledge of mechanics principles and of vehicle fixing techniques and procedures. Any important
changes made to the vehicles or to specific fixing operations will be promptly reported by updates to this
manual. Nevertheless, no fixing work can be satisfactory if the necessary equipment and tools are
unavailable. It is therefore advisable to read the sections of this manual relating to specific tools, along
with the specific tool catalogue.
The descriptions and illustrations given in this publication are not binding. While the basic specifications
as described and illustrated in this manual remain unchanged, PIAGGIO reserves the right, at any time
and without being required to update this publication beforehand, to make any changes to components,
parts or accessories, which it considers necessary to improve the product or which are required for
manufacturing or construction reasons.
Not all versions/models shown in this publication are available in all countries. The availability of single
versions should be checked at the official Piaggio sales network.

A) ESSENTIAL WARNINGS
The check or in any case the intervention on the circuits of the devices for the electronic ignition can
be done with relative ease by the electronic repairers of Service Station Workshops; it is essential,
however, that they take observe the notices below, since, in case of failure to observe, they could
irreparably damage the devices.
Allinspectionoperations of the system involving disconnection of cables (verification of the connections
and devices that are part of the ignition circuit, therefore including the main key switch) must be made
with the engine off: otherwise the control unit could be irreparably damaged.
The ignition circuit works on AC, and obviously,
must be definitely separated from that of DC
In fact the latter, powered by the battery and dy-
namotor, serves only for the service user groups
(city lights, stop, horn, lights, headlight, etc.).

If there is a connection of two circuits, i.e., if the

be instantaneous deterioration of the control
unit. It is therefore necessary and important
that,incaseofremovalordisconnectionofcables,
particularlyof thosewhichdepend onthe mainkey
switch and the control unit, during reassembly pay
attention to correctly reconnect each cable to the

ways advisable to consult the electrical circuit
diagrams.

For obvious reasons it is essential that, in case of
replacement of one or more devices in the system
(main switch, stator unit of the flywheel, control
unit) during reassembly, a device is used that is
similar totheexisting one: if in fact similar devices
were used, but not specific to the same ignition
system, they would not work, risking irreparable
damage to the control unit.
KEY:
1= White
2= Red
3= Green
B) INSPECTIONS TO BE PERFORMED IN THE EVENT OF IGNITION IRREGULARITIES
In the event of failure and abnormal operation of the ignition, whose causes are not detectable by a
visual inspection, it is necessary first to replace the control unit with a corresponding, safely functional
one.Rememberthatthedisconnectionsandconnectionstoreplacethecontrolunitmustbe performed
when the engine is off.
General guidelines APE TM Benzina
GEN - 8

Ifreplacingrestorestheignitionoperation,thefault
liesinthe control unit, which obviously needs to be
replaced. In the event that the failure persists, it is
necessary to carry out checks on the alternator
and on the stator components as follows:
After a visual inspection of the connections, stator
and couplings, measurements are carried out on
thechargingcoilandtheignitioncoil usinganOhm
meter, capable of detecting resistance from 1 to
1000 ohm, as follows:
- Connect the instrument between the WHITE ca-
ble and the RED cable; there must be continuity
and ohmic value (430 to 480 ohm);
KEY:
1) White
2) Red
3) Green
- Connect the + terminal of the instrument with the
WHITE cable and the - terminal of the instrument
with the RED cable there must be continuity and
ohmic value (7 to 9 ohm).
KEY:
1) White
2) Red
3) Green
If failures are detected in the inspections of the charging coil and ignition coil, proceed to replace the
damaged parts.
If there is no tool available to check the stator, when it is established that the ignition problem is not
related to the power control unit nor to other visible causes (bad connections, damaged cables, dam-
aged spark plug), proceed to replace the complete stator. In relation to what described in the preceding
paragraphs we recommend, therefore, to include in the control tools an Ohm meter with the charac-
teristics outlined above.
C) IGNITION TIMING CHECK
APE TM Benzina General guidelines
GEN - 9

The timing check may be useful for example if the motor is not operating properly (start-up difficulties;
decreased performance and power; difficult or irregular recovery speed etc.); if the failure does not
depend on the carburetion, it may be caused by irregularities of the ignition timing.
Thispossibilityis,however, consideredquite raresince, dueto thecharacteristics ofthe ignitionsystem,
the timing adjustment remains unchanged over time; since the problem arises in most cases from ir-
regularoperationofthecontrolunit, tobesure pleasefollowthe stepsoutlinedon thesideforverification
of the aforementioned device.
If however, after checking the carburetion and the
control unit, the desired improvements are not ob-
tained and there is doubt whether the anomalies
are due to the ignition timing, proceed to check the
latter, operating as follows:.
1) Insert, into the hole (1) a rod of Ø 5 mm.; run the
engine manually until when the end of the rod,
comingintocorrespondencewith theother holeon
the rotor, does not fit.
In this condition the engine is in ignition advance position.
2) Makea mark with whitepainton the fan cover,incorrespondence with the flapof the flywheel bearing
the reference for the timing.
3) Connect a stroboscopic lamp (type TECNOTEST 130/P or other similar) at ignition; the connection
will be made directly on the spark plug or on the H.V. cable, etc. depending on the type of stroboscopic
lamp available and the specific operating instructions. Then start the engine and bring it to about
4000-5000 rpm.
4) The engine will be properly timed to the lamp when the two marks are aligned, or at most, moved to
within a tolerance range of 4° (i.e., within 2° to the right and 2° to the left of alignment position).
5) If the mark of the flywheel rotor is shifted compared to the crankcase more than the allowed tolerance
(or other major irregularities appear during the check), replace the stator or the control unit.
N.B.
FOR VEHICLES OF NEXT PRODUCTION, THE FAN COVER WILL BE FITTED WITH A REFER-
ENCE FOR TIMING, SO THE OPERATIONS DESCRIBED IN POINTS 1 AND 2 WILL NOT BE
NECESSARY.
